Incidentally Serendipity 3 is also home to the world's most expensive sundae. For $1,000 and 48-hours notice, you can truly get one of these creations made in celebration of the restaurant's 50th anniversary. The sundae is made of five scoops of the richest Tahitian vanilla bean ice cream infused with Madagascar vanilla and covered in 23K edible gold leaf. It is then drizzled with the world's most expensive chocolate, Amedei Porceleana, and covered with chunks of rare Chuao chocolate, which is from cocoa beans harvested by the Caribbean Sea on Venezuela's coast. The masterpiece is suffused with exotic candied fruits from Paris, gold dragets, truffles and Marzipan Cherries. It is topped with a tiny glass bowl of Grand Passion Caviar, an exclusive dessert caviar, made of salt-free American Golden caviar, known for its sparkling golden color. It's sweetened and infused with fresh passion fruit, orange and Armagnac. The sundae is served in a baccarat Harcourt crystal goblet with an 18K gold spoon to partake in the indulgence served with a petite mother of pearl spoon and topped with a gilded sugar flower.
